123 - How to Connect Peripherals

Connect Computer Peripheral to Back Panel. The back panel is the portion of the motherboard that allows you to connect external devices such as your monitor, speakers, keyboard, and mouse.

Back panel connector

The back panel is the portion of the motherboard that allows you to connect external devices such as your monitor, speakers, keyboard, mouse, modem, printer, scanner, copier and also a power source. You can see the back panel connector on the back of your CPU unit.

This connection allows instructions and data to flow between the computer and the device. These computer ports are also commonly referred to as the Input/Output ports (I/O ports).

How to connect peripherals into back panel connector

01 • Connect the power cord connector into PSU power port

02 • Connect the PS/2 connector into motherboard built in mouse port and keyboard port

03 • Connect the USB connector into universal serial bus port

04 • Connect the VGA connector into display monitor port

05 • Connect the JACK connector into sound system port

06 • Connect the RJ45 connector into ethernet port

A: Power Connector - The power supply unit provides all the electrical power needed by all the components of your computer system. The power connector is a 3-prong male connector which enables you to connect a power cable to the computer Port A to obtain power from an electrical outlet.

B: Mouse Port - The mouse is a pointing device that enables you to move and select items on the screen. The mouse is connected to Port C. This port is also called a mini-DIN or PS/2 connector.

C: Keyboard Port -The keyboard is one of the input devices that allows you to enter instructions and information into a computer. The keyboard is connected to Port D. This port is also known as the mini-DIN or PS/2 connector.

D: USB Port - (USB) Acronym for Universal Serial Bus. This port can connect up to 127 peripherals (such as mice, modems, keyboards, etc.) all at once. It also enables hot-swapping which is being able to connect and disconnect peripherals without powering down the PC.

E: Parallel Port (Printer Port) - The parallel port is a 25-pin female connector (DB-25). It is an interface for connecting external devices such as a printers and computers that require relatively high bandwidth. It supports bi-directional communications.

F: Serial Port (COM Port) - This port is a 9-pin male connector (DB-9) and enables serial communication with a transfer rate of 1 bit. This port can be used to connect a computer peripheral such as a modem, mouse, etc.

G: Game Port - The game port is a 15-pin female analog port used to connect game controllers such as joysticks. It can also be used as a Musical Instrument Digital Interface (MIDI) Port for connecting a computer peripheral such as a synthesizer and is located on the sound card.

H: Monitor Port - The monitor is connected to Port I which is a 15-pin female connector called a VGA Port. Present computers also use a DVI port for connecting a monitor. New monitors come with DVI and VGA ports.

I: Sound Port - All Motherboards have three audio ports. Green port for Audio out. this is used to connect headset or two speakers or 2.1 surround system. Pink connector for mic, this is used to connect microphone. Blur color connector for Line in, this connector is used to connect Tv tuner card or capture cards.

J: Ethernet Port (RJ-45) - The ethernet port accepts an ethernet cable which allows you to communicate on a network that runs Transmission Control Protocol/Internet Protocol(TCP/IP).This port resembles a regular phone jack but is slightly wider and is generally located on the Network Interface Card (NIC) or integrated on the motherboard.

Computer hardware peripherals

A peripheral is a piece of computer hardware that is added to a computer in order to expand its abilities. The term peripheral is used to describe those devices that are optional in nature, as opposed to hardware that is either demanded or always required in principle. There are all different kinds of peripherals you can add your computer. The main disctinction among peripherals is the way they are connected to your computer. They can be connected internally or externally.
